Horizontal tear of the meniscus occurs most commonly in older patients. The tear begins initially with a simple horizontal cleavage which divides the meniscus into superior and inferior leaves resembling a fish mouth and which may become a flap or more complex tear with time if subjected to repeated injury. Thirty-four patients(36knees/40menisci) with horizontal tear of the meniscus, treated with arthroscopic partial meniscectomy except in 3 extensive tears at Ulsan University Hospital from Jan. 1993 to Jun. 1996, were analyzed to investigate the factors that may be associated with this type of meniscal tear, and the results were as follows; 1. The tears commonly occurred in labor workers(61.7%) and without obvious trauma history(67.6%), and the average age at the time of surgery was 44 years. 2. The most common site of the tear was posterior horn of the medial meniscus (62.5%). 3. The 40 horizontal tears consisted of 12 horizontaVcleavage(30%), 3 horizontaVflap(7.5%), and 25 horizontaUdegenerative complex tears(62.5%). 4. Degenerative changes were frequently noted in both arthroscopy(69.5%) and roentgenography (72.2%).

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

The traditional treatment for the femoral shaft fractures in children is closed reduction by continuous traction, usually for 2–3 weeks, until the fracture has achieved partial stability, followed by spica cast immobilization. Fifty three cases, from 3 to 10 years of age, has been treated with closed reduction and immediate application of hip spica csst; all of them were closed fractures of femoral shaft and were not associated with head, abdominal, or vascular injuries. Any angulations in excess of acceptable ranges were corrected with wedging the cast; any overridings in excess of acceptable ranges were corrected by skeletal traction for 1 week, followed by incorporation of the pin to the cast. The resultant overriding and angulation of fragments were within acceptable ranges, and complications were not significant.This method of treatment not only is likely easy in nursing care and comfortsble to the patients but also has some advantages of short stay in the hospital, better utilization of hospital beds, and costsaving. This immediate hip spica cast immobilization seems to be a good method of treatment for the femoral shaft fracture in children.

The goals of orthopaedic management of pelvic ring injuries are to achieve anatomical reduction and secure fixation of fragment and mobilize the patient as early as possible. Previously, pelvic ring injuries have been treated by a wide variety of conservative methods. Their application, however, necessitated a prolonged period of recumbency with associated likelyhood for many complications and did not facilitate accurate reduction and stabilization of most types, resulting in pelvic deformity, non-union and late sacroiliac joint instability. During the past decade, experience with techniques of external and internal fixation of the pelvis has grown and the goals of the methods include provision for sufficient pelvic stability in satisfactory position so that immediate postoperative bed-to-chair transfers can be undertaken and complications due to prolonged recumbency and pelvic deformity can be markedly reduced. We reviewed 47 cases of unstable pelvic ring injuries treated at the depatment of orthopaedic surgery, Dongkang Hospital from January 1984 to December 1987, and the results were as follows ;1. The highest incidence was in the 4th decade and sex ratio between male and female was 1.6:1 2. The most common cause of injury was traffic accident (68.2%) followed by falling down accident (19%) 3. Associated injuries occurred in 28 cases (60%): injuries of the extremities were most common (30%) followed by head injury (13%) and genitourinary tract injury (11%). 4. According to classification of Pennal et al, lateral compression injury was most common (51.1%). Bucholz Group II injury was 57% of all and Group III, 43%. 5. Operative methods, with which 21 cases were treated, were anterior external fixation with AO apparatus or symphyseal plating in Bucholz Group II injuries ; and external fixation, internal fixation (anterior and/or posterior) or both, in Group III injuries. 6. Advantages of operative treatment of unstable pelvic ring disruptions were, by giving stability, early mobilization; easy care of associated injuries, open wounds and nursing; prevention of possible complications of prolonged recumbent position; rapid reduction of pain; and prevention of late complications such as lumbosacral or pelvic pain and gait disturbance.

The author reviewed 148 cases of phalangeal and metacarpal fractures of the hand, excluding distal phalangeal and carpal bones, in 75 patients treated at the Department of Orthopaedic Surgery, Dong-Kang Hospital, from January, 1984 to December, 1987. We obtained the following results ; 1. Better results were obtained in younger patients, transveres or spiral fractures, and cases immobilized in MP joint flexion. 2. Factors that led to worse results included older age, comminuted fracture, wide displacement, intra articular fracture, associated tendon injury, intraarticular pin placement. 3.In case of K-wire fixation, dorsal placement of the wire revealed better result than volar one.

The patella is an important component of the extensor mechanism of the knee. It serves to increase the mechanical advantage of the quadriceps muscle by increasing its lever arm. Therefore, if possible, when the patella is fractured, it should be repaired rather than excised. Present surgical techniques for the patellar fractures utilizes principles of anatomic reduction with repair of any associated retinacular tears, rigid internal fixation, and early institution of joint motion exercises. To compare the efficacies of the commonly used wiring techniques, we performed tension tests with transversely bisected patellar models fixed with circumferential wiring, Magnuson wiring, modified tension band wiring and modified tension band wiring combined with circumferential wiring. Also, we reviewed 66 surgically treated patellar fractures from Jan. 1984 to Dec. 1988, when we had given every effort to preserve the patella using modified tension band wiring or modified tension band wiring combined with circumferential wiring. l. According to the results of the tension tests, modified tension band wiring and Magnuson wiring were more rigid than circumferential wiring and the rigidity of modified tension band wiring was much increased when combined with circumferential wiring. 2. Of the 66 cases, 46 cases were treated with modified tension band wiring combined with circumferential wiring, and the remainder were treated with modified tension band wiring. 3. On the whole, good and excellent results were achieved in 87.9% (58 cases). Unsatisfactory results were obtained in 15.0% of cases treated with modified tension band wiring and in 10.9% of cases treated with modified tension band wiring combined with circumferential wiring. 4. Most of the unsatisfactory cases were so severely comminuted that could not be achieved anatomic reduction, rigid internal fixation and early joint motion exercises.
